Playing doctor is considered by most child psychologists to be a normal step in childhood sexual development between the ages of approximately three and six years, although it can be a source of discomfort to some parents, when they discover their children are engaging in such an activity.[7] Parenting professionals often advise parents to view such a discovery as an opportunity to calmly teach their children about the differences between the sexes, the importance of modesty, and respecting the privacy and bodies of other children.[4]
